i don't know how you answer for this when you look at the president of the united states and he comes up short at a loss for words. we later learned he had longer remarks to deliver, but he himself couldn't get through it. the question, as we said, at the top of the broadcast lester as you have been asking on the coverage all day, who would kill these kids? where does this come from? how do we recover? it may be unanswerable. and the answer may be just to try to get through it. and a reminder to stay with your late local news tonight for the latest on this story. i'll remind all of you, my colleague lester holt will be joined tomorrow morning for a special live edition of "the today show." matt lauer and savannah guthrie will be there. from our entire team, on the ground in newtown, connecticut, after a dark day across the country. i'm brian williams, thank you for joining us.
